盘截面形式对混凝土扩盘桩抗拔破坏影响的试验

摘要

In this paper,according to several common forms of the concrete expanded-plates pile currently,it is initially established small model test research programs in undisturbed soil. By changing the sectional form of the bearing expanded-plates,it can be observed that the whole fail-ure process of the concrete expanded-plates pile under uplift forces,so as to provide reliable reference for similar problems.%针对目前国内混凝土扩盘桩的常用截面形式，确立了原状土小模型试验研究方案，通过改变扩大盘的截面形式，实现全过程观察扩大盘截面形式对混凝土扩盘桩抗拔破坏的影响状况，为类似问题的研究提供可靠的依据。
